PVVNG (A), APVVNG (A), PVVNG (A) -LS, APVVNG (A) –LS

Applying area and purpose

• Cables are designed for transmission and distribution of electrical energy in stationary installations for a rated alternating voltage of 6-35 kV with a nominal frequency of 50 Hz for networks with a grounded and insulated neutral;
• For laying in the ground (in trenches) if the cable is protected from mechanical damage;
• Designed for operation when laying in the ground, regardless of the degree of corrosion activity of soils;
• It is allowed to lay these cables in the air, in cable structures
• Cables are designed for laying on the tracks without limiting the difference in levels;
• For laying along routes with complex configuration
• Cables of execution ng (A) -LS are used for laying:
• - in rooms, tunnels, canals, mines, dry soil and in the open air under a canopy
• - in bundles
• - at facilities where requirements for reduced smoke and gas emissions are imposed (nuclear power plants, metro, large industrial facilities, high-rise buildings)
